A few tiny improvements that I had sitting in an edit buffer. More to come.

Much, much more. :-)

+* The ordering comparison operators (``<``, ``<=``, ``>=``, ``>``)
+  raise a TypeError exception when the operands don't have a
+  meaningful natural ordering.  Thus, expressions like ``1 < ''``, ``0
+  > None`` or ``len < len`` are no longer valid.  A corollary is that
+  sorting a heterogeneous list no longer makes sense -- all the
+  elements must be comparable to each other.  Note that this does not
+  apply to the ``==`` and ``!=`` operators: objects of different
+  uncomparable types always compare unequal to each other, and an
+  object always compares equal to itself (i.e., ``x is y`` implies ``x
